Explosion proof Runaway Switch HFKPT1-20-35 Explosion proof Runaway Switch HFKPT1-20-35 Explosion proof Runaway Switch HFKPT1-20-35 Two stage Runaway Switch Product Technical Parameters Description:
1. Product Overview (HF) KPT1 series Two stage Runaway Switch is mainly used in conveying systems in industries such as metallurgy, power, coal and rock, mining, and chemical engineering. It is a sensing element for conveyor automation control *. This product can be used for detecting conveyor belt deviation, preventing material overflow and other faults caused by belt deviation. This product is widely used in conveyor belts due to its convenient installation and reliable switching performance. This product is internally certified by the National Institute of Electrical Safety Supervision and Inspection (NEPSI) and meets the requirements specified in the GB12476.1-1990 standard. Scope of application: 1. Conventional belt conveyor 2. Underground and plain track support belt conveyor 3. Ship loading and unloading system 4. Stacking/reclaiming conveyor 5. Tilting and shuttle conveyor 6. Crane/excavator boom limit 7. Skirt feeder/conveyor 8. Heavy limit switch 9. Special processing, nickel plated and stainless steel rollers 10. Auxiliary flag alarm 11. Wrench (used for tightening cover plates) 2. Working environment 1. Environmental temperature: -40 ℃~60 ℃ 2. Relative humidity not exceeding 85% 3. Sea level not exceeding 2000m 4. Service life: switch action 100000 times 5. Insulation voltage: AC1000 test for 1 minute 6. Touch point capacity:≤ AC380≤ 3A7. Protection level: HFKPT1 IP55 HFKPT1-N IP67 III. Product features: 1. Universal installation design allows the anti deviation switch to be installed freely on the top or bottom of the conveyor longitudinal beam. 2. Durable cast aluminum shell, protection standard NEMA4, and special surface treatment is optional for special environments. 3. The integral cover plate is easy to connect and adjust. 4. The cover plate can be removed without removing the action rod. 5. The rated speed of the action rod bearing is 5000 revolutions per minute, suitable for belt speeds less than 6.35 meters per second. 6. The normal angle adjustment range of the action lever is 22.5 degrees. When the normal angle is 10 degrees, the alarm contact will act, and when the normal angle is 20 degrees, the shutdown contact will act.
